Set in the summer after the end of high school, "Summer of 8" follows eight close friends having as much fun together as they can at the beach before they part ways to head off to college. Longstanding couple Jesse and Lilly debate whether or not to maintain a long distance relationship, while Aiden works up the nerve to tell his friend Serena about his romantic feelings for her. Meanwhile, Bobby is worried about going to college alone, Emily is worried about her lack of sexual experience, and Jen is seemingly unworried about anything.
